Purpose: The study aimed to explore hyperintense areas in the cisternal segments of the cranial nerves using magnetic resonance imaging (MRI).
Methods: Seventy outpatients underwent thin-sliced, coronal constructive interference steady-state (CISS) sequence and sagittal T2-weighted MRI following conventional MRI examination.
Results: With the coronal CISS sequence, hyperintense areas were located in the central parts of the olfactory bulbs in 65.7% of patients. For the intracranial optic nerve and optic chiasm, hyperintense areas were detected in 98.6% of the CISS sequences and 100% of the T2-weighted images. In the optic tract, hyperintense areas were detected in 51.4% of cases. In 35% of the patients who underwent the CISS sequence, the intracranial optic nerves were considerably compressed by the internal carotid and anterior cerebral arteries, with hyperintense areas similar to those in patients without vascular compression. Hyperintense areas of the cisternal segments of the oculomotor nerve and trigeminal root were identified in 52.9% and 87.1% of the patients, respectively.
Conclusions: The hyperintense areas found within the cisternal segments of the cranial nerves delineated on the coronal CISS sequence and sagittal T2-weighted imaging may indicate the intracranial part of the glymphatic pathway through the cranial nerves. The cranial nerves may function as part of the glymphatic pathway.

Background And Purpose: Whether differences in the O-methylguanine-DNA methyltransferase () promoter methylation status of glioblastoma (GBM) are reflected in MRI markers remains largely unknown. In this work, we analyze the ADC in the perienhancing infiltration zone of GBM according to the corresponding status by using a novel distance-resolved 3D evaluation.
Materials And Methods: One hundred one patients with wild-type GBM were retrospectively analyzed.

We present a rare case of a patient with co-occurring exercise-induced acute kidney injury (AKI) and rhabdomyolysis. A 67-year-old man was referred to our department with AKI. Five days before referral, the patient had sudden-onset loin pain while banging and kicking on a door in a holding cell at a police station.

Objective: To clarify the clinical features of recurrent myelin oligodendrocyte glycoprotein antibody-associated cortical encephalitis (MOGCE) in adults.
Methods: We present an adult case of recurrent MOGCE and summarize the clinical symptoms, imaging findings, treatment and prognosis of this phenotype as per a systematic review of the literature.
Results: We identified 9 adult patients with recurrent MOGCE.

This study aimed to evaluate changes in cerebral blood flow and perioperative outcomes in patients with unilateral symptomatic carotid artery stenosis before and after carotid artery stenting (CAS), providing insights to guide surgical decision-making. Ninety-six patients with moderate to severe unilateral symptomatic carotid artery stenosis (>50%) admitted to the Neurology Department of the Second Affiliated Hospital of Zhejiang University from June 2023 to April 2024 were included. All patients underwent CAS and magnetic resonance imaging, including diffusion-weighted imaging (DWI) and 3D quasi-continuous arterial spin-labeled perfusion imaging, within 3 days preoperatively and on the third postoperative day.

Brats-Toolkit and DeepBraTumIA generally provide accurate segmentations, particularly for the most common round-shaped or well-demarked tumors, where: (1) gross tumor segmentation correctly includes necrosis and contrast enhanced tumor in 100% and 97.
